You see, when I draw a digital stamp for you, I do a lot of thinking.
Take this House Mouse stamp here, it's "Pincushion" by Stampendous.
As the illustrator (not me) drew out this scene of mice, thimbles, and a big pincushion, they went through a long thought process.
"The large mouse has two feet that he's lifting into the air on each jump. His ears are pinnned back in excitement. There are pins in the cushion but they're not right where the mouse is jumping, otherwise he'd stab himself. The sleeping mice are completely relaxed with limp ears and limp tails..."
Yes, artists actually think these kinds of thoughts as they draw.
This thinking process means that the artist is completely familiar with every single object in their drawing. They know what everything is, why it looks the way it looks, and where one object stops and another object starts.
They understand everything inside the image because they thought it through before they drew it.
